Abstract
A knife assembly includes a knife blade of which a front edge is a cutting edge, a holder for supporting the knife blade, a clamp for clamping the knife blade onto the holder, and a fastening mechanism for securing and clamping the knife blade between the clamp and the holder with the cutting edge protruding at a front side of the assembly. The holder has a frontal portion which is the foremost portion of the assembly at a bottom side of the knife blade and of which a foremost contact point is, in clamped state, in contact with a bottom side of the knife blade at a first distance from the cutting edge. The clamp includes front portions which protrude forward and into valleys of the knife blade and which have leading edges that protrude beyond said foremost contact point and create a crumple zone in front of the holder.
